SUMMARY:Doppler Time-of-Flight Rendering
DESCRIPTION:Technical Papers\n\nJuhyeon Kim and Wojciech Jarosz (Dartmouth
  College), Ioannis Gkioulekas (Carnegie Mellon University), and Adithya Pe
 diredla (Dartmouth College)\n\nWe introduce Doppler time-of-flight (D-ToF)
  rendering, an extension of ToF rendering for dynamic scenes, with applica
 tions in simulating D-ToF cameras. D-ToF cameras use high-frequency modula
 tion for illumination and exposure, and measure the Doppler frequency shif
 t to compute the velocity of dynamic objects. The time-varying scene geome
 try and high-frequency modulation functions used in such cameras make it c
 hallenging to accurately and efficiently simulate their measurements with 
 existing ToF rendering algorithms. We overcome these challenges in a twofo
 ld manner: To achieve accuracy, we derive path integral expressions for D-
 ToF measurements under global illumination and compute these integrals wit
 h unbiased Monte Carlo estimates. To achieve efficiency, we develop a tail
 ored time-path sampling technique that combines antithetic time sampling w
 ith correlated path sampling. We demonstrate experimentally that our sampl
 ing technique achieves ×100 acceleration compared to naive time-path sampl
 ing across different D-ToF camera models. We provide an open-source simula
 tor that serves as a digital twin for D-ToF imaging systems, allowing imag
 ing researchers, for the first time, to investigate the impact of various 
 modulation functions, material properties, and global illumination on D-To
 F imaging performance.\n\nRegistration Category: Full Access\n\nSession Ch
